Hi!

I hope you understand what I try to describe, because my englisch is not the best.

I have Suse 8.1 and confixx 2.x. On my server postfix runs as MTA. I installed amavisd-new, clamav and spamassassin.
Everything works fine, only mails with german umlauts are not sent. I always get an errormail :
Code:
INVALID HEADER (INVALID CHARACTERS OR SPACE GAP) 

Non-encoded 8-bit data (char FC hex) in message header 'Subject' 
 Subject: Re: denic vu - Kostenlose_Domains f\374r alle\n 
                                             ^ 

This nondelivery report was generated by the amavisd-new program 
at host xxx.de. Our internal reference code for your message 
is 13070-04. 


WHAT IS AN INVALID CHARACTER IN MAIL HEADER? 

 The RFC 2822 standard specifies rules for forming internet messages. 
 It does not allow the use of characters with codes above 127 to be used 
 directly (non-encoded) in mail header (it also prohibits NUL and bare CR). 

 If characters (e.g. with diacritics) from ISO Latin or other alphabets 
 need to be included in the header, these characters need to be properly 
 encoded according to RFC 2047. This encoding is often done transparently 
 by mail reader (MUA), but if automatic encoding is not available (e.g. 
 by some older MUA) it is the user's responsibility to avoid the use 
 of such characters in mail header, or to encode them manually. Typically 
 the offending header fields in this category are 'Subject', 'Organization', 
 and comment fields in e-mail addresses of the 'From', 'To' and 'Cc'. 

 Sometimes such invalid header fields are inserted automatically 
 by some MUA, MTA, content checker, or other mail handling service. 
 If this is the case, that service needs to be fixed or properly configured. 
 Typically the offending header fields in this category are 'Date', 
 'Received', 'X-Mailer', 'X-Priority', 'X-Scanned', etc. 

 If you don't know how to fix or avoid the problem, please report it 
 to _your_ postmaster or system manager. 


Return-Path&#58; <wwwrun@mail.xxx.de> 
Your message <20040406095117.6254C5C804E@mail.xxx.de> could not be delivered to&#58;

  554 5.6.0 Message with invalid header rejected, id=13070-04 - Non-encoded 8-bit data &#40;char FC hex&#41; in message header 'Subject'
When you look in the Subjectline, you see Subject: Re: denic vu - Kostenlose_Domains f\374r alle\n. This should normaly be "für alle" in the end.

Thanks for you help!
